the use of knowledge learned by science; examples include computers, video games, and robots

observation

careful watching that can include measurements and descriptions and sketches or drawings of exactly what is seen

Hypothesis

a statement about a problem that can be tested

science

the process of trying to understand the world around you. A set of steps that can be followed to help find out about something or to solve a problem.

trials

the number of times an experiment is repeated

Is communication and important skill in science? Why?

Yes, scientists depend on each other to share what they have learned. It is important to communicate results because two scientists may have gotten two different results. That means one or both of the scientists are wrong and they will have to run more trials.

They communicate with each other by recording everything they observe in a scientific journal. In their scientific journals they might express their ideas about what they are investigating, make a sketch of what they see, or explore different opinions on the subject. They also might make a data table and record information in that.

Independent Variable

This variable is the one that is changed by the scientists. In an experiment there is only one of these kind of variables.

How can we distinguish between science and technology?

Technology is not science. It is a use of knowledge learned THROUGH science.

Dependent Variable

changes in response to the change made to the independent variable

What is science?

the process of trying to understand the world around us. A set of steps that can be followed to help find out about something to solve a problem.
